TUBULAl-t BEDSTEAD AND OTHER FRAME.

itteiiifigd.

To all whom it may concern Be it known that I, GEORGE HOLDEN, a citizen of the United States, and a resident of Flushing, in the county of Queens and State of New York, have invented certain new and useful Improvements in Tubular Bedstead and other Frames, of which the following is a specification.

The invention relates to improvements in frames composed of tubing, such as the head and foot frames of metal bedsteads, and it consists in the novel features and structure hereinafter described, and particularly pointed out in the claims.

The invention pertains more particularly to novel and efficient means for firmly connecting the ends of one tube to the sides of two other tubes, as, for illustration, the ends of the horizontal tubular rails of a headframe or foot-frame of a metal bedstead with the sides of the tubular post members thereof.

The invention is applicable to many articles of furniture and the like constructed from sections of tubing, but I illustrate the same in this application in connection with the manufacture of metal bedsteads and for securing the upper and lower horizontal rails of the head or foot-frame of the bedstead to the tubular posts thereof.

In accordance with my invention I form on the ends of one tube or rail suitable projecting members and provide in the facing sides of two other tubes to be connected by said tube or rail suitable slots or openings to receive said projecting members, While within said other tubes 1 provide suitable springs to engage the said projecting members after they have entered said slots or openings and firmly bind the tubes together, said springs operating as clutches to engage the ends of one tube and secure the same against the facing sides of the other tubes.

The invention will be fully understood from the detailed description hereinafter presented, reference being had to the accompanying drawings, in which:

Figure 1 is a perspective view of a footframe or head-frame of a bedstead having its upper and lower horizontal rails connected with the tubular post-members by means embodying my invention; Fig. 2 is an enlarged horizontal section, on the dotted line 22 ofFig. 3, through the corner post and spring therein and a portion of one of the Specification of Letters Patent.

The posts 18 and their parts correspond with each other and the rails 16, 17 corre-' zontal member 22 and a vertical member 23.

The body portions of the members 23 are bent inwardly toward each other and their outer edges are flanged outwardly, as at 24, from each other, whereby said members become provided in their outer faces with recesses to receive and interlock with certain springs to be hereinafter described. The lower rail 17 corresponds exactly with the upper rail 16 except that it is usually somewhat less in vertical diameter than said upper rail.

Each post 18 is formed in its inner side wall in line with the rails 16, 17 with openings or vertical slots 25 adapted to snugly receive the projections on the ends of the --rails, said projections in the assembling of the parts being passed through said openings or slots so as to be fully within the posts. Then the rails are applied to the posts the inner edges of the recesses 20, 21 evenly engage the outer face of the post.

Within each post 18 and in line with the openings or slots 25 therein, I provide springs 26 to interlock with the projections on the ends of the rails when the latter are applied to the posts and thereby attach the ends of the rails to the posts. I preferably form the springs 26 from one integral strip of metal 27 bent into a three-sided outline snugly fitting within the interior of the postand engaging three sides thereof, as shown in Fig. 2. The outer or free ends of the spring-members 26 are deflected toward each other and each is formed at its free end, by slitting and return-bending the metal thereat, with upper and lower corresponding locking members or fingers 28 of hook form and an intermediate finger 29, which preferably will not be bent inwardly to the same extent as the fingers 28.

The three main features of my invention are shown in Figs. 5, 6 and 7, and in assembling these features the strip 27 carrying the springs 26 is inserted within the post from the end thereof and pushed to position With relation to the openings or slots 25 (Fig. 4) or until the upper and lower locking fingers 28 are in line with said slots and the fingers 29 are between them, andthereupon the rail is applied to the post, the projections on the end thereof being entered through the said openings or slots 25 and pushed inwardly until the edges of the recesses 20, 21 firmly engage the face of the post. When the projections on the rail are pressed through the openings or slots in the post, their vertical members 23, at the outer vertical edges of the flanges or lips 24, move against the inclined faces of the fingers 28 of the springs 26 and force said springs outwardly from each other to a sufficient extent to allow said projections to pass into the post, and then as the said projections reach their final position within the post the said flanges 24 pass just beyond the said fingers 28 and allow the springs 26 to spring toward each other and carry said fingers behind said fianges 24 and into the recessed outer sides of the members 23 of said projections, with the result that said springs and projections become interlocked and firmly secure the end of the rail against the face of the post. When the rail has been secured to the post by the aforesaid springs and projections, it cannot be pulled from the post and it cannot move upwardly or downwardly since the projections snugly fit the openings or slots 25. It is desirable that the springs 26 be-prevented during any handling or use of the bed from shifting from their correct position, and this result is attained in my construction by the tight fit of the strip of metal 27 within the post and from the fact that the fingers 29 on the springs stand between the upper and lower projections on the rail and that the recesses in the outer faces of the vertical members 23 of said projections are, above the upper fingers 28 and below the lower fingers 28, closed and therefore confine said fingers in a way to prevent their having any vertical shifting movement. Of course the springs 26 may be secured in position in other ways, as by riveting them to the post, but my purpose has been to avoid such riveting and at the same time to present a very durable and eflicient structure.

In the modification of my invention shown in Figs. 8 to 12 inclusive, the post is numbered 30, the rail 31 and the springs 32, said springs preferably being formed from an integral strip 33 bent into a three-sided outline to fit within the post, as shown in Fig. 8. The rail 31 is recessed in its upper and lower end edges, as at 34, leaving vertical channel-shaped projections 35, one being at each side of the end of therail and composed of an extending portion 36 of the side of the rail and upper and lower horizontal flanges 37 created out of the metal of the top and bottom of the rail. The projections 35 are formed in their sides with vertical slots 38. The post 30 is formed in its face with two parallel vertical slot-s 39 to snugly receive the projections 35 on the end of the rail. The springs 32 are deflected toward each other at their outer or free ends, and thereat said springs are formed with inwardly extending locking flanges 40 adapted to enter and snugly fill the slots 38 in the rail when the rail is applied to the post. In assembling the parts the springs are inserted within the post and then the rail is applied to the post, the projections 35 of the rail being inserted through the slots 39 of the .post and while moving inwardly causing the springs to flex outwardly until the slots 38 reach the flanges 40 of the springs, whereupon saidflanges will be projected into said slots and firmly connect the rail with the pos Both forms of my invention hereinbefore described enable a very eflicient and rapid assembling of the rails and posts of a metal bedstead or like article and improve and lessen the manufacturing cost of the beds and the like.

1 have presented two embodiments of my invention in order that it may be under stood that the invention is not confined to specific details of form and construction and is capable of modification.

hat I claim as my invention and desire to secure by Letters-Patent, is:
